Abstract
⺠Multifunctional nanoparticles with a gold plasmonic shell and Fe3O4 magnetic core for simultaneous fast concentration and identification of bacteria using surface-enhanced Raman spectroscopy (SERS). ⺠Multifunctional nanoparticles condensed to a highly compact dot serving as a sensitive SERS-active substrate. ⺠Quick concentration of bacteria by applying an external point magnetic field to a mixture of bacteria and nanoparticles. ⺠Efficient differentiation of bacteria via principle component analysis of SERS spectra acquired from the dot area.
